India’s ARC Stablecoin vs the Digital Rupee: Why RBI Is Playing Both Sides of the Crypto War

India’s central bank has spent the better part of three years warning the world that private stablecoins are a threat to monetary sovereignty, financial stability, and the global payments architecture. Then, in early 2025, Polygon Labs quietly partnered with Indian fintech Anq to build a rupee-backed stablecoin called ARC — Asset Reserve Certificate — targeting institutional markets. It is scheduled to launch in 2026. So, is the Reserve Bank of India contradicting itself? Not quite. The full picture is more nuanced, more strategic, and far more instructive about where India’s digital finance architecture is heading.

What is ARC?

ARC stands for Asset Reserve Certificate, a rupee-denominated stablecoin developed through a joint venture between Polygon Labs — the team behind one of Ethereum’s largest Layer-2 scaling networks — and Anq, a Mumbai-based institutional fintech firm. The project represents one of the most significant blockchain infrastructure announcements to emerge from India’s regulated financial sector.

At its core, ARC is a 1:1 INR-backed digital asset. Every ARC token in circulation is matched by an equivalent value held in Indian government securities and treasury bills — not dollar reserves, not algorithmic mechanisms, not offshore cash pools. The sovereign-grade collateral is custodied domestically, designed to eliminate the capital-flight risk that regulators associate with dollar-denominated stablecoins like USDT.

Key technical and structural features of ARC include:

Polygon blockchain infrastructure — leveraging Polygon’s PoS chain for settlement speed and transaction cost efficiency
Uniswap v4 hooks — protocol-level compliance controls embedded directly into smart contracts, enabling KYC/AML enforcement without off-chain intermediaries
UPI integration — ARC is designed to interface with India’s Unified Payments Interface, enabling institutional on-ramp and off-ramp flows
Whitelisted institutional accounts only — minting and redemption are restricted to authorized corporate and institutional counterparties; there is no public issuance
No retail access — individual users cannot hold or transfer ARC directly; it is a business-to-business settlement instrument

The 2026 launch timeline positions ARC within a maturing regulatory window. India’s cryptocurrency tax framework (30% flat tax on gains, 1% TDS on transfers) has been in force since April 2022, and ongoing discussions around a national crypto policy suggest the government is building toward formal asset classification rather than outright prohibition.

What is the e-Rupee (CBDC)?

The e-Rupee is the Reserve Bank of India’s Central Bank Digital Currency (CBDC) — a digital form of the Indian rupee issued and backed directly by the central bank. Unlike commercial bank deposits or stablecoins, the e-Rupee carries the same legal status as physical currency notes: it is a direct liability of the RBI.

The RBI launched its retail CBDC pilot in December 2022 and has steadily expanded participation. As of the latest available data:

120 million+ transactions have been processed on the retail e-Rupee platform
₹28,000 crore (approximately $3.4 billion) in total transaction value has been settled
8 million+ users have registered for the retail e-Rupee wallet
Over 13 public and private sector banks are participating in the pilot

The e-Rupee operates across two distinct segments:

Retail e-Rupee

Targeted at consumers and small businesses. Accessible through participating bank apps, the retail CBDC allows person-to-person and person-to-merchant payments. It does not earn interest — deliberately, to prevent disintermediation of commercial bank deposits — and operates with tiered KYC requirements.

Wholesale e-Rupee

Designed for interbank settlements, government securities transactions, and large-value payment clearing. The wholesale CBDC pilot has focused on reducing settlement times in call money markets and government bond transactions, with several major banks conducting live trades using the platform.

Why RBI Rejects Private Stablecoins

The RBI’s opposition to privately issued stablecoins is well-documented and rooted in three interconnected concerns: monetary sovereignty, capital flight, and systemic risk.

RBI Deputy Governor T. Rabi Sankar has been the most vocal critic. In a widely cited 2022 speech, he stated that crypto assets, including stablecoins, “do not have any underlying cash flows” and argued they derive value purely from speculative demand — making them structurally different from currencies, securities, or commodities. His position has remained consistent since: private digital money threatens the state’s exclusive authority to control money supply and credit conditions.

The RBI’s Financial Stability Report has flagged stablecoins as a source of macrofinancial risk, citing:

Capital flight — Widespread adoption of dollar-backed stablecoins like USDT or USDC by Indian residents would effectively dollarize domestic savings, weakening INR demand and reducing the RBI’s ability to manage exchange rates
Reserve run risk — If a major stablecoin’s peg breaks (as TerraUSD did in May 2022, erasing $40 billion in value in 72 hours), the contagion can spill into conventional financial markets
Regulatory arbitrage — Stablecoins operating outside the banking system bypass CRR, SLR, and other prudential requirements that apply to bank deposits, creating an uneven playing field
AML/CFT exposure — Bearer-style digital cash can facilitate illicit flows across borders without correspondent banking oversight

None of these concerns are unique to India. The Financial Stability Board (FSB), BIS, and IMF have all published warnings with similar themes. But India’s position has been among the most assertive globally.

How ARC Is Different

ARC has been architected specifically to address every objection the RBI has raised against private stablecoins. Whether this architecture will satisfy regulators in practice remains to be seen — but the design choices are deliberate.

INR-only backing in sovereign securities — There is no dollar peg, no algorithmic mechanism, and no offshore custodian. Capital stays in India, in instruments the RBI itself manages
No public minting — ARC cannot be created by retail users or crypto-native protocols. Only whitelisted institutional accounts with full KYC and corporate registration can issue or redeem tokens. This eliminates the uncontrolled supply expansion that characterizes USDT
Protocol-level compliance — Uniswap v4 hooks embed compliance logic into the smart contract layer itself. A transaction involving a non-whitelisted wallet will fail at protocol execution, not just at the application layer. This is a technically stronger enforcement model than off-chain blacklists
UPI integration — By anchoring to India’s domestic payment rail, ARC operates within the regulated financial infrastructure rather than in parallel to it
No retail access — The most politically sensitive risk — ordinary Indians converting savings into a private digital currency — is structurally blocked by design

In effect, ARC is not trying to replace the rupee or compete with the e-Rupee. It is closer to a tokenized money market instrument — a programmatic, on-chain wrapper for government securities that institutional participants can use for settlement, treasury management, and smart contract-native financial operations.

What This Means for Indian Businesses

For corporate finance and treasury teams operating in India, ARC represents a meaningfully different set of capabilities compared to both traditional bank transfers and the retail-focused e-Rupee.

Treasury Management

Companies holding idle cash in overnight instruments could tokenize those positions as ARC, enabling real-time collateral mobility across trading counterparties or subsidiaries without waiting for settlement windows. The 1:1 backing in government securities means the token carries near-zero credit risk while remaining programmable.

Automated Settlements

Supply chain finance, invoice factoring, and intercompany settlements currently involve multi-day clearing cycles and significant reconciliation overhead. ARC’s smart contract infrastructure — particularly Uniswap v4 hook-enabled conditional execution — allows settlement to be triggered automatically on contract milestones (delivery confirmation, invoice approval, regulatory sign-off) without manual bank instruction.

On-Chain Commerce

For B2B e-commerce platforms, logistics companies, and export-import businesses, ARC could provide a programmable payment rail that integrates natively with blockchain-based trade finance, escrow, and compliance systems — all within the INR currency zone and without the FX exposure of USD stablecoins.

The addressable market is significant: India’s B2B digital payments market was valued at over $200 billion in 2024, and institutional adoption of on-chain settlement infrastructure — even at the margin — could drive substantial volume through ARC’s rails.

The Bigger Picture

India’s approach to digital money is increasingly coherent as a strategy rather than a contradiction. The RBI is not anti-blockchain — it is anti-disintermediation. It objects to private money that operates outside sovereign control, not to the technology itself.

ARC, if it receives regulatory clearance, would validate a model that several emerging market central banks are watching closely: privately issued, institutionally restricted, domestically collateralized stablecoins that expand the programmable money ecosystem without displacing sovereign currency or enabling capital flight.

Countries like Brazil (with its DREX CBDC), the UAE (with its Digital Dirham), and Nigeria (with the eNaira) are grappling with the same tension — how to capture the efficiency gains of blockchain-based finance without surrendering monetary control. India’s two-track approach — a sovereign CBDC for retail, a tightly controlled institutional stablecoin for B2B — may become the reference architecture for the next generation of emerging market digital finance.

The e-Rupee gives the RBI direct digital currency issuance. ARC, if approved, gives Indian institutions programmable settlement infrastructure. Together, they create a financial system that can participate in the global blockchain economy on India’s own terms — with compliance controls, capital restrictions, and sovereign backing baked in from the start.

Whether ARC ultimately clears the regulatory bar in 2026 is uncertain. What is certain is that the question is no longer whether India will have a tokenized rupee ecosystem — it is which design wins.
